Termite control question?

assuming they are subterranean termites, the termites live under ground, come up to feed on the wood then have to return back to the nest for moisture. You need to remove the wood from next to the house, you will have to move the wood pile for the house treatment to be done along that wall anyways. In the future avoid stacking wood, or anything that hides any section of the home next to it, where you do store the wood be sure to put it on a metal rack to keep the wood from touching the ground.
